Substrates should be primed with Visqueen HP Tanking Primer prior to application. Application Visqueen Self Adhesive Membrane is for use in vertical tanking or horizontal self adhesive applications, such as underground basements, lift pits or retaining walls when installed in accordance with BS8102:2009. It is recommended that substrates are always primed with Visqueen HP Tanking Primer, concrete, masonry or steel at or below ground level. Adequate ventilation must be ensured at all times during application in accordance with our health & safety datasheet. Visqueen Self Adhesive Membrane is not suitable for any roofing or podium applications. Installation Guidelines Installation should be in accordance with BBA Certificate No. 12/4924, BS Code of Practice 102 and BS 8102:2009. All surfaces to which the membranes are to be applied should have a smooth finish, be dry and free from dust, loose particles and frost. The surface should then be sealed using Visqueen HP Tanking Primer and allowed to dry thoroughly. Vertical surfaces of brickwork and blockwork should be dry and rendered to give an even surface. Brickwork and blockwork not rendered should be pointed to give a smooth surface without sudden changes in level. All lap joints should be a minimum of 150mm and must be pressed and rolled to form a continuous bond and ensure watertightness. A suitable drainage system should be designed and incorporated in accordance with the requirements of BS8102:2009. The membrane can be installed in normal site conditions provided the air temperature is not below 5°C.
